The necessary information for an adequate development of human beings is contained in some “books” called genes; they are written in an “ink” called DNA. Our total number of genes is found in the 46 chromosomes that we inherit from our parents, and it should have no excesses or deficiencies, since these could cause serious diseases and malformations, and even put our life in danger.
Human embryos have a high rate of chromosomal alterations, especially in the case of couples with fertility problems, such as recurrent miscarriages and implantation failures. For this reason, when we are in the In Vitro Fertilisation (IVF) laboratory with a couple’s embryos, we already know it is very likely that many of them are chromosomally abnormal.
Only embryos with no excesses or deficiencies in their DNA have the capacity to produce a healthy newborn. Therefore, by identifying and selecting an embryo with a full chromosome count, we manage to guarantee that the embryo has maximum capacity to produce a healthy child. […]
